Code with no clear architecture, no documentation, no coding standards, no tests, many security-issues, a lot of hardcoded stuff, written by people forced to use a completely new technology stack and messing up, of course.

But we are not allowed to change anything, of course.

We have to keep coding in that style and with the tools present in the project. For uniformity, of course.

I managed to work on that code for 2 years... Recently it dawned on me that I don't give a crap anymore.
I quit, of course.
